Having a highly ranked recruiting class and a bunch of four-star signees sounds good in the spring and summer, but it's a different story when the season begins. The freshmen who are game-ready are the ones who get the playing time, no matter their star rating. Here's a look at the five Big 12 schools getting the most from their true freshmen:

1. Texas Tech: The Red Raiders practically earn this top spot by default by relying on two true freshmen at quarterback. Baker Mayfield made a big first impression, but it seems the battle is opening back up after two solid games from freshman Davis Webb, and the imminent return of Michael Brewer. Still, going 4-0 with two rookies behind center makes coach Kliff Kingsbury’s bunch a worthy No. 1 on this list.

Tech has played eight other true freshmen in 2013, and a few are making solid contributions. Receiver Dylan Cantrell has six catches for 56 yards, linebacker Malik Jenkins has recorded five tackles and a pass breakup and receiver Carlos Thompson already has a 73-yard kick return and 35-yard punt return.

2. Oklahoma: Is it possible Oklahoma’s best running back is its fourth-string freshman? Keith Ford, the gem of the Sooners’ class, has rushed for 66 yards and a touchdown on 11 carries and wowed in OU’s last game against Tulsa.

3. West Virginia: Of all the new skill players who joined West Virginia’s offense this year, who would’ve expected Daikiel Shorts would be the Mountaineers’ leading receiver and Wendell Smallwood would be their No. 2 back? Shorts has 12 catches for 151 yards and two touchdowns, and Smallwood has 139 yards and a touchdown on 18 carries thus far.

A total of seven true freshmen have played for WVU this season, and four of them are defensive backs. Corner Daryl Worley is off to a nice start with six tackles, a tackle for loss and a pass breakup.

4. Oklahoma State: Many expected Ra’Shaad Samples to be OSU’s breakout true freshman receiver, but so far that distinction belongs to Marcell Ateman. He has hauled in eight passes for 92 yards, good for fourth-best on the team.

Freshman kicker Ben Grogan has hit all 19 of his extra-point attempts and is 1-for-2 on field goals, and defensive backs Jordan Sterns and Deric Robertson have combined for eight tackles this season.

5. Baylor: Baylor might have two of the conference’s most talented true freshmen in receiver Robbie Rhodes and defensive tackle Andrew Billings, but they haven’t had to do much so far. Rhodes has 65 receiving yards and Billings has recorded three tackles, including one tackle for loss. Kiante’ Griffin is also contributing at linebacker with three tackles and 1.5 tackles for loss.

TCU can also make a case for the No. 5 spot. The Frogs don’t have a Devonte Fields-caliber breakout star yet, but receiver Ty Slanina has two reception and is currently listed as a starter, and former ESPN 300 prospect Tevin Lawson is breaking into the rotation at defensive tackle with two stops already.
